Which protocol must be enabled?

16. A service provider hires you to design its new managed CE offering to meet these requirements

• The CEs cannot run a routing protocol with the PE

• Provide the ability for equal or unequal ingress load balancing in dual-homed CE scenarios.

• Provide support for IPv6 customer routes

• Scale up to 250.000 CE devices per customer.

• Provide low operational management to scale customer growth.

• Utilize low-end (inexpensive) routing platforms for CE functionality.

Which tunneling technology do you recommend?

17. A customer has a functional requirement that states HR systems within a data center should be segmented from other systems that reside in the same data center and same VLAN. The systems run legacy applications by using hard-coded IP addresses.

Which segmentation method is suitable and scalable for the customer?

20. Which two factors must be considered for high availability in campus LAN designs to mitigate concerns about unavailability of network resources? (Choose two.)

21. Refer to the exhibit.

Company XYZ BGP topology is as shown in the diagram. The interface on the LA router connected toward the 10 1.5.0/24 network is faulty and is going up and down, which affects the entire routing domain.

Which routing technique can the network administrator use so that the rest of the network is not affected by the flapping issue?

22. Company XYZ is running OSPF in their network. They have merged with another company that is running EIGRP as the routing protocol. Company XYZ now needs the two domains to talk to each other with redundancy, while maintaining a loop free environment. The solution must scale when new networks are added into the network in the near future.

Which technology can be used to meet these requirements?

23. In an OSPF network with routers connected together with Ethernet cabling, which topology typically takes the longest to converge?

24. How many fully established neighbour relationships exist on an Ethernet with five routers running OSPF as network type broadcast?
